At the current natural-increase rate of 0.9% annually, the population would double in roughly 78 years if the rate held. Real trajectories bend as fertility, mortality and migration shift, which is why the chart below shows both history and projection.
Among its first-level divisions, the largest by our modelled allocation is Stung Treng, holding an estimated 21.1% of the national population. The full breakdown of all 25 states and regions is in the table below — regional figures outside Sudan are modelled estimates built on real region names, and are flagged as such.
Literacy stands near 85.0% and adult smoking prevalence around 17.0%, with life expectancy at about 56.5 years. Baselines come from UN World Population Prospects, the World Bank, WHO surveys, WorldPop and HDX; the counters project them forward in real time — the method, and every caveat, is documented on our data sources page.
